Title: Secure mutual network authentication and key exchange protocol
Inventor: GROSSE ERIC
IPC: G06F21/31
Filed: 2001-02-09
Abstract: Secure communication protocols are disclosed in which two parties generate a shared secret which may be used as a secure session key for communication between the parties. The protocols are based on Diffie-Hellman type key exchange in which a Diffie-Hellman value is combined with a function of at least a password using the group operation such that the Diffie-Hellman value may be extracted by the other party using the inverse group operation and knowledge of the password. In one embodiment, each of the parties explicitly authenticates the other party, while in another embodiment, the parties utilize implicit authentication relying on the generation of an appropriate secret session key to provide the implicit authentication. Typically, the parties will be a client computer and a server computer. In accordance with other embodiments of the invention, in order to protect against a security compromise at the server, the server is not in possession of the password, but instead is provided with, and stores, a so-called password verifier which is a function of the password and where the password itself cannot be determined from the value of the password verifier.

Filed: 1999-04-14
Abstract: Trans-xanthophyll ester concentrates having a trans-xanthophyll ester content of at least four times greater and preferably at least nine times greater than the cis-xanthophyll ester content are obtained.  Xanthophyll ester concentrates having a total xanthophyll ester content of at least 40 wt.% and preferably greater than about 55 wt.% are also obtained, A method of obtaining a trans-xanthophyll ester concentrate of high purity includes contacting plant material containing xanthophyll esters with a hydrocarbon solvent for a time sufficient to extract xanthophyll esters from the plant material, separating the hydrocarbon solvent and extract dissolved therein from the remaining plant material, evaporating the hydrocarbon solvent from the dissolved extract to obtain a crude xanthophyll ester concentrate, admixing the crude xanthophyll ester concentrate with an alcohol at approximately ambient temperature to dissolve non-xanthophyll impurities and cis-xanthophyll esters from the concentrate and removing the alcohol containing impurities and cis-xanthophyll esters from the crude traps-xanthophyll concentrate to obtain a purified trans-xanthophyll ester concentrate. By using only the corollas of marigold flowers, lutein ester concentrates of high purity are obtained with pesticide residues absent from the concentrate at parts per billion detection levels.

Patent CA-2367264-A1 (CA)
Title: Coated film forming method and apparatus therefor
Inventor: SUZUKI YASUJI
IPC: B05D1/00
Filed: 2002-01-08
Abstract: A coated film forming method is capable of readily forming a coated film of a thermoplastic material on a coated region of an inner peripheral surface of a cylinder. A nozzle, through which a molten paste of a thermoplastic material kept molten is discharged, is disposed toward an inner peripheral surface of a cylinder. The nozzle is moved along a rotational central line of the cylinder while rotating the cylinder and discharging the molten paste from the nozzle. Centrifugal force acting on the cylinder being rotated leads to spreading of the molten paste applied to the inner peripheral surface of the cylinder. Viscosity of the molten paste, a rotational speed of the cylinder and a speed of movement of the nozzle are set so as to keep the molten paste discharged from the nozzle from being scattered to a region other than the coated region.

Inventor: GELLER HERBERT M
IPC: A61K38/00
Filed: 2000-04-28
Abstract: We developed an assay to quantify neurite behavior at sharp substrate boundaries and found that neurites demonstrated a strong preference for fnA-D  when given a choice at a poly-L-lysine/fnA-D interface. Furthermore, neurites preferred cells that over expressed the largest but not the smallest tenascin-C splice variant when given a choice between control cells and cells transfected with tenascin-C. The permissive guidance cues of large tenascin-C  expressed by cells were mapped to fnA-D. We demonstrate that neurite outgrowth and guidance are facilitated by distinct sequences within fnA-D. Hence, neurite outgrowth and neurite guidance mediated by the alternatively spliced region of tenascin-C are separable events which can be independently regulated.

IPC: A61B5/296
Filed: 2000-07-07
Abstract: In a method and system for producing a higher quality electromyographic sign al describing myoelectrical activity of an electrically active region of a subject's muscle, a plurality of EMG signals representative of the electrica l activity of the electrically active region of the subject's muscle are sense d through an array of electrodes. A weighting function is applied to the detected EMG signals to thereby produce weighted signals, this weighting function containing correction features for the relative locations of the center of the electrically active region and the electrodes. Finally, a sum or mean of a feature of the weighted signals is calculated to thereby produce t he higher quality electromyographic signal. Prior to calculating the sum or mea n of the weighted signals, electromyographic quality of the weighted signals i s evaluated, and the weighted signals or sum or mean of the weighted signals whose evaluated quality is insufficient are replaced. Alternatively, the higher quality electromyographic signal is replaced in response to weighted signals of insufficient quality. The method and system can also be used to determine signal strength or frequency contents of a signal falling outside the array of electrodes.
